In this tutorial, we design a scalable interactive object system in Unreal Engine 5 using Blueprint Interfaces. The session focuses on building a clean, decoupled communication architecture that eliminates excessive casting and hard references.
We will implement multiple interactive actors—such as doors, switches, and pickup items—using a shared interface contract, and integrate them into a line-trace-based player interaction system. The goal is to demonstrate how interface-driven design improves scalability, modularity, and long-term maintainability in production-level projects.
This tutorial emphasizes architectural thinking and best practices for Blueprint communication in Unreal Engine 5.
